AWR2243: Post Processing failed in mmWave Radar

Part Number: AWR2243

Hi, I am facing the same problem, and I cannot get an idea of how the previous post problem was solved.

When I choose a .bin file and click the postproc button, it returns

[10:21:07]  [RadarAPI]: ar1.StartMatlabPostProc("C:\\ti\\PostProc\\adc_data\\master_0000_data.bin")

It seems that opening the post-processing window works for me. But the window is blank as below

Hello Haocheng,

Can you try restarting mmWave Studio in this case and see if it helps.

As a workaround, you could also try "standalone post processing". This is particularly useful when the data is already captured from a previous session and the user just needs to post process the data using Studio.

Just follow the steps as highlighted in section 8.2.2 of mmWave_Studio_cascade_user_guide.pdf.

Regards,

Ishita

Yes, it is still blank in Matlab Windows, not as same as the user_guide.pdf, which has several plot figures. I think this might be the Matlab fault. But I have the matlab2015aSP1 32bit runtime (8.5.1 as the user_guide indicated) installed. In the figure I posted, the left side is my situation, no graphs. In the right-hand side, you could tell that the .bin file has been loaded because the frame size has been recognized.

Hello Haocheng,

Yes, I feel the same. I believe there was an issue with the MATLAB download itself.

Try installing it again, and if that also doesn't help, try installing mmWave Studio as well again.

Regards,

Ishita

Yes, it is the fault of Matlab. I still did not get that Why this SDK is running on a 32-bits Matlab? Could you tell me your information about the test machine (system version, bits, Matlab version)? My computer is windows 10 64bits, Matlab 2015aSP1. I don't know how to resolve the dependency problem. It would be appreciated If you could fix the bug for the present new hardware and software.

Hi, I find a solution about the error. Install a patch file from https://ww2.mathworks.cn/support/bugreports/1179769. And extract the file to Matlab folder. Then the problem solved. Hope this could help the other people. BTW, you should update the applications :).
